European homologation valid for: APRILIA ZD4TEA - ZD4VFB - ZD4VFD - ZD4THG.
The homologation does not restrict mounting on other vehicles. Exhaust manufactured by pressing from 1.5 mm thick sheet steel.
Please note:
retrofit systems generally always have more power than the original exhaust. In order to obtain approval, they are throttled at the factory, which can result in a shift in the power band. In order for the scooter to reach its full power and speed, it may therefore be necessary to adapt the engine to the new exhaust with different variator weights, clutch springs and/or carburetor jetting, even if it is to be used throttled on a standard engine.
